This part is designed for applications that need fast read throughput for execute-in-place (XIP) code shadowing, configuration storage, or data logging in embedded systems, industrial controllers, networking gear, and automotive infotainment or telematics units. ## 133 MHz Quad SPI — what it buys you The 133 MHz clock rate with Quad I/O (four data lines) yields a theoretical peak read throughput of 532 Mbps. In practice, that means a 16 MB firmware image can be loaded from this Flash into system RAM in under 250 ms, assuming a 50 MHz controller-side SPI clock. For systems booting from serial NOR, this speed gap between the Flash and the host controller's SPI peripheral is often the bottleneck — the S25FL256LAGMFI000 keeps the Flash side of the link from being the limiter. The 16-pin SOIC wide-body (7.50 mm width) footprint is a standard layout for serial NOR Flash, making it straightforward to drop into existing board designs that already use a 16-SOIC SPI Flash. No exposed pad to route, so the decoupling cap sits close to the supply pin without thermal-via constraints.","metaTitle":"Infineon S25FL256LAGMFI000 256Mbit SPI NOR Flash, 133 MHz","metaDescription":"Infineon S25FL256LAGMFI000 256Mbit serial NOR Flash in 16-SOIC.
